PROCESS OF BURNING BRICK.

SPECIFICATION formingpart of Letters Patent No. 708,394, dated September2, 1902. Application filed May 23, 1902. Serial No. 108,679. (Nospecimens.)

T0 (ZZZ whom it mlcty concern:

Be it known that I, JOHN PEOK, a citizen of the United States, and aresident of Haverstraw, in the county of Rockland and State of NewYork,haveinvented anew and Improved Process of Burning Brick, of whichthe following is a full, clear, and exact description.

The object of this invention is to cheapen, as well as to render moreeffective, the work of burning brick in kilns. Heretofore oil and woodhave been used extensively for this purpose; but soft coal has not beenfound capable of use in this manner, owing to the dense smoke whichrises therefrom and tends to clog the interstices of the kiln. Thisinvention seeks to enable soft coal to be employed, and it attains adecided advantage over other manners of burning the brick, since it ismuch cheaper and also produces a more regular and reliable fire.

In carrying out the invention after the kiln has been set up in theusual manner I fire the same through the arches with atomized oil. Thisproduces an intense heat, which pervades the entire kiln and heats thebrick. After this has been attained the oil-supply is cut off and a fireof soft coal or other suitable fuel is built in the arches, and thisfire is maintained until the kiln has been entirely burned. The smokerising from the coal passes through the interstices of the kiln and iscompletely consumed therein, owing to the high heat of the bricksattained by the oil burning, as before mentioned.

I am aware of the patent to Hamilton, No. 340,780, dated April 27, 1886,which discloses the process of burning brick with a fuel formed of cokeand coal mixed. My invention is not to be confounded with the Hamiltonprocess, since I claim specifically the use of atomized oil in the firststages of the firing and then the use of soft or bituminous coal oranalogous fuel. The smoke rising is consumed in the interstices of thekiln, and thus the full benefit of the fuel is derived and an extremelyregular and effective burning of the kiln is attained.

Having thus described my invention, I claim as new and desire to secureby Letters Patent-- The herein-described process of burning brick inkilns, which consists first in subjecting the kiln to the action of afire fed with atomized oil and maintaining this fire until the kiln hasbeen heated, and second, in stopping said oil-fire and continuing theburning of the kiln by a fire fed with soft or bituminous coal or othersimilar fuel.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOHN PEOK.
